The rails are pins named like VCC, GND or 5V, battery holders' terminals, and holes noted with a rail's name (\"+9V\"). With expectNets, every connection missing from the board or extra on it is an error. Enabled saved requirements also check intended connections, missing components/pins and unused pins; unspecified pins produce an incomplete-coverage warning, not a full match. Wires crossing each other are fine (insulated jumpers) and only listed in notes. Fix all errors before making a link.
